Greek Fire is an explosive gas, which seems to be stored in liquid. A more powerful alternative is The Black Powder.
- In real life, Greek Fire was the secret weapon of the Byzantine Empire, and, as it continued to burn on water, was the key to the repeated defenses of Constantinople throughout the centuries. The earliest use of the term seems to refer to a generic ship-mounted flame-thrower device, but later came to refer to a specific compound whose formula was a state secret. It was therefore deadlier than gunpowder, which became more popular because it was easier to use.
